RepositoryImpl attempts to close active session twice on shutdown
-----------------------------------------------------------------
Key: JCR-3246
URL: https://issues.apache.org/jira/browse/JCR-3246
Project: Jackrabbit Content Repository
Issue Type: Bug
Components: jackrabbit-core
Affects Versions: 2.4
Reporter: Jan Haderka
Priority: Critical
On shutdown sessions are being closed twice which lead to the exception being logged as shown below. As far as I can tell {{RepositoryImpl}} has system sessions in the list of active sessions which is why it tries to close them twice - first time when closing all active sessions {{(RepositoryImpl.java:1078)}} and second time when disposing workspace {{(RepositoryImpl.java:1090)}}.
